Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs feet
- Provide gelatinous connective tissue that becomes tender with long boiling and gives body to the dish.
- Pigs ears
- Provide cartilage that softens during boiling, giving a tender, chewy texture when sliced.
- Vinegar
- Adds acidity that sharpens the flavour of the rich meat and balances the fat.
- Butter
- Adds fat and richness to serve alongside the fried pieces.
The step that matters
Fry the pieces. The boiled meat is already cooked and tender, so frying should be brief and hot enough to brown the surface without drying it out. Dried pieces brown better because surface moisture would otherwise steam rather than crisp.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, butter):
- Mustardthe original
- Shallotfits about as well
- Onionfits about as well
- Cucumberfits about as well
Fit is the average pairing score against vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
